BACKGROUND OF THE DISCLOSURE

1. Field of the Disclosure

The present disclosure relates to exercise devices. In particular, it relates to foam roller exercise devices.

2. State of the Art

Foam rollers are currently utilized by physical therapists and Pilates practitioners in the performance of a number of physical exercises to enhance core strength of a patient's back and abdominal region. In use, a person typically lies on his or her back with the foam roller between the user's back and a floor surface. The foam roller is typically aligned along the user's spine. These exercises facilitate balance, develop good posture and emphasize balance awareness.

These foam rollers are typically about 6 inches in diameter and about three feet long, and made of a semi rigid polyethylene foam or other semi rigid, yet marginally compressible plastic foam material so as not to be impermissibly uncomfortable to a user lying on the roller. Since the roller is typically about 6 inches in diameter, a person lying on her back is spaced a substantial distance from the floor. While this facilitates achieving balance when the user attempts to keep her arms off the floor, a six inch distance may be less than desirable for use by a physical therapist's patient during rehabilitation efforts. A smaller diameter foam roller may thus be desirable in such instances.

Foam rollers provide excellent tactile prompts for the user and are especially helpful in core stability training. Because foam rollers are cylindrical and inherently unstable, they challenge the user's conscious awareness, provide sensory motor challenges, and enhance balance reactions, muscle re-education motor planning and neural flexibility.

Foam rollers have been produced in 3 inch and 2 inch diameters but none has achieved the success that the 6 inch diameter roller has. However, these rollers do not spread the user's body weight over as large a surface area as the 6 inch roller, and thus are somewhat less comfortable to use properly. In addition, the smaller diameter produces an undesirably small radius of curvature that is uncomfortable to use. Larger diameter rollers undesirably space a user's body too far from the support floor to be practically useful.

Therefore there is a need for a roller that spaces a user's body closer to the floor yet provides a comfortable curved surface upon which to lie, and also provides a larger radius of curvature for use by those who find the 6 inch diameter rollers uncomfortable to use. There is also a need for a roller design with different curvatures that accommodates users of different body types, weights, and physical conditions.

SUMMARY OF THE DISCLOSURE

A foam roller exercise device in accordance with the present disclosure accomplishes a shape and form to accommodate users of different body types, weights, and physical conditions. In one aspect, the foam roller exercise device is elongated and includes a first portion. The first portion comprises a uniform cross-sectional shape, a first curved outer surface having a first radius of curvature and a second curved outer surface spaced from the first curved outer surface. The second curved outer surface has a second radius of curvature greater than the first radius of curvature. The first and second curved outer surfaces are joined by separate outer surfaces.

In one embodiment, the first radius of curvature is centered about a first longitudinal axis through the elongated foam roller exercise device and the second radius of curvature is centered about a second longitudinal axis parallel to the first longitudinal axis. The first longitudinal axis is parallel to and spaced from the second longitudinal axis. For example, the distance from the first longitudinal axis to the first curved outer surface is greater than the distance from the first longitudinal axis to the second curved outer surface and the distance from the second longitudinal axis to the first curved outer surface is less than the distance from the second longitudinal axis to the second curved outer surface. In one embodiment, the separate outer surfaces joining the first and second curved outer surfaces are concave and parallel to and spaced from each other.

In another embodiment, the elongated foam roller exercise device includes first and second separable portions together forming a generally right circular cylindrical body about a central axis. The first portion may have a first curved outer surface having a first radius of curvature about the central axis and a second curved outer surface spaced from the first curved outer surface. The second curved outer surface may have a second radius of curvature about a second axis parallel to and spaced from the central axis. In such an embodiment, the first radius of curvature is different from the second radius of curvature. The first curved outer surface and the second curved outer surface are joined by third surfaces. The third surfaces may be concave, and/or flat, and parallel to and spaced from each other. The second portion of the elongated foam roller exercise device preferably has a uniform cross-sectional shape complimentary to the first portion so that together the portions form a generally right circular cylindrical body.

In a further embodiment, the elongated foam roller exercise device includes first, second and third separable portions. The first and second portions fit together as described above. The third portion has a uniform cross-sectional shape, a first curved outer surface, and a second curved outer surface spaced from the first curved outer surface. The uniform cross-sectional shape is complimentary to the generally right circular cylindrical body formed when the first portion and the second portion are placed together.

The second radius of curvature is greater than the first radius of curvature. The first curved outer surface 112 and the second curved outer surface 114 are joined by separate outer surfaces 116. The foam roller exercise device 100 may be any polymer foam material suitable to achieve comfortableness and proper use of the foam roller exercise device 100, such as a polyurethane foam, polyethylene foam, polystyrene foam, and/or closed-cell foam, to name a few.

In one embodiment, the first radius of curvature may be centered about a first longitudinal axis A through the elongated roller and the second radius of curvature may be centered about a second longitudinal axis B parallel to the first longitudinal axis A. The first longitudinal axis A is preferably parallel to and spaced from the second longitudinal axis B. The separate outer surfaces 116 may be any shape and/or length suitable to enable the first curved outer surface 112 and the second curved outer surface 114 to be joined. For example, the separate outer surfaces 116 may be concave, flat, wavy, and/or zigzag, to name a few. In one embodiment, the distance from the first longitudinal axis A to the first curved outer surface 112 is greater than the distance from the first longitudinal axis A to the second curved outer surface 114.
